MEANS FOR ATTACHING SHIPS BOATS TO AND DETAGI-IIN Gr THEM FROM TACKLESUSPENDED FROM DAVITS OR THE LIKE.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed September 12, 1919. Serial No. 323,422.

To all whom it may concern:

Be it known that I, AUGUSTUS WILLIAM LOUIS SCHERMULY, a subject of theKing of Great Britain, residing at Stonecroft, Stone Cot Hill, Sutton,in the county of Surrey, England, have invented new and useful ImprovedMeans for Attaching Ships Boats to and Detaching Them from TackleSuspended from Davits or the like, of which the following is aspecification.

My invention relates to means for suspending and releasingships boatsfrom the said means being of the kind in Which the" falls and tackleblocks suspended from the davits, are connected, by links, or theequivalent, to'inclined hooks (one usually being a lever hookmanipulated for re lease) secured to the boat, toward its'ends, and afore-and-after connected to the lower ends of the. said tackle, acts toprevent outward movement of the said ends of the tackle relatively toeach other and thereby, until the boat is released, maintains the links,or the equivalent, in engagement with their respective hooks, therelease being effected by slacking a rope connection extending betweenthe devices which connect the boat with the falls from the davits.

The object of my invention is to provide simple and efficient meanswhich will insure the boat taking the water on an even keel whatever maybe the position the boat is in when released from the falls, and willalso insure secure suspension of the boat, nonliability to accidentaldetachment, and rapid release when required, while, obviating, orlessening, liability to the occupants of the boat being injured by thetackle when released.

According to my invention the falls and lower blocks of the tackle bywhich the boat is suspended from the ships davits are connected with theboat by links, or loops, engaging upwardly inclined hooks secured to theboat, the said blocks being connected by a tie-rope, or fore-and-aftermade, or arranged, so that it can be, in eifect, lengthened andshortened; it, when shortened, holding the said links, or loops, inengagement with the said hooks and when lengthened allowing the links,or loops, under the weight of the boat, to slip from the said hooks, andrelease the boat. The tie-rope, or foreand-after, is provided with avery simple device, as hereinafter described, by

means of which, by the removal of one simple securing device which holdstwo hinged parts parallel with each other, the tie-rope, or fore andafter becomes lengthened and thus the release of the boat can be instantaneously effected by one person using one hand.

I will describe with reference to the accompanying drawing anarrangement in accordance with my invention.

Figure l is a longitudinal section of a boat with an arrangementaccording to my invention applied thereto. Figs. 2 and 3 show, in theshorter and longer positions re spectively, the device by means of whichthe effective length of the tie-rope, or foreand-after? is altered.

The said device consists of, or comprises,

two members, one of which (that consisting of the two pieces marked A)is connected (at B) by the pin a with the lower end of one of thetackle-blocks of the falls from the davits, the other member (thatmarked A consisting of a slotted link, hinged to the inner end of thefirst mentioned member A by the pin a and engaged by a loop a or thelike, connected with one end of the tie-rope, or fore-and-after, C, theother end of which is connected (at B to the tackle-block. The saidmembers A and A are foldable upon eachother and capable of being securedin that position by a fastening such as the pin a which, when removedfrom the holes at a will allow the members A and A to open out from eachother upon the hinge pin a which connects the said members. The pull onthe tie-rope, or fore andafter C tends to turn the link member A 011 thehinge pin a to bring it into line with the other member A, but it isnormally held in its folded, and securing, position (Fig. 2) by theretaining pin a (with which the projection a in the member A engages)but upon the release of the said pin a the said link member A under thepull of the tie-rope, or fore-and-after, C, turns upon the pin a whichconnects it with the other member A (as in Fig. 3) and virtuallylengthens the tie-rope, or foreand-after C, so that the suspendingtackle is not then held in the securing position by the said tie-rope,or fore and after G, and the weight of the boat causes the hooks, E, orother securing means carried by the boat to slip off the Z? orequivalents, of the suspending tackle, and release the boat upon an evenkeel. I

If desired, there may be a device, such as that described, at each endof the tie-rope, or fore-and-after C, but generally one only, asillustrated, will be preferable.

The aforesaid tie-rope, or after C can be arranged well above theposition in which the occupants of theboat would be, and the extensibledevice is so secured that its hinged member A turns upward, or away,from the boat, so that liability to the occupants being injured by thetackle is obviated, while, as the tackleblocks of the two falls remainconnected, they are easily laid hold of when the boat is to be attachedto the falls. 1

What I'claim is v 1. A boat supporting and releasing apparatuscomprising. a pair of inclined hooks secured at opposite ends of theboat and faced away from each other, a pair of davit falls, one for eachhook, a slip member on each fall adapted to engage its hook, tie meansextending between the fall elements to hold said slip members insupporting engagement with the inclined hooks, and means for, releasingsaid tieto vpermit the escape of the said slip members from the inclinedhooks under the weight of the boat.

'2. A boat supporting and releasing apparatus comprisinga pair ofinclined hooks secured at opposite ends of the boat and faced away fromeach other, a pair of davit falls, one for each hook, a slip member oneach fall adapted to engage its hook, tie

means extending between the falls, a take-up.

device arranged in said tie to draw said slip IIlBIIlbBlSiIltOsupporting engagement with the inclined hooks, and means for releasingsaid take-up device to permit the tie to so 001ml of this patent may beobtained for fore-andlengthen that the slip members escape the inclinedhooks under the weight of the boat.

3. A boat supporting and releasing apparatus comprising a pair ofinclined hooks secured at opposite ends ofthe boat and faced away fromeach other, a pair of davit falls, one for each hook, a slip member oneach fall adapted to engage its hook, the means, extending between thefalls, said tie means comprising a link adapted to be moved intooverlapping position with relation to a cooperating member in the tie todraw said slip members into supporting engagement with the inclinedhooks, and read ily releasable means for engaging said link insaidoverlappin'g position but serving on release to free said linkandpermit the tie to solengthen'that the slip'members escape the inclinedhooks under the weight of the boat.

4. A boat supporting and releasing apparatus comprising a pair ofinclined hooks secured at oppositeends of the boat and faced away fromeach other, a pair of davit falls, one for each hook, a slip "membe-roneach fall adapted to engage its hook, tie means permanently. connectedto and extending between said falls, a take up' device in the tie fordrawing the slip members on the falls into supporting engagement withthe inclined hooks, and means for releasing said take-up to permit thetie to so lengthen that the slip members escape the hooks under theweight of the boat. 7

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
